Yes, you can absolutely get married in a castle in Wales in 2026, as many are "Approved Premises" for civil ceremonies. Iconic locations like Castell Coch, Caerphilly Castle, and Cardiff Castle offer dedicated wedding packages. In 2026, the process requires you to book the venue first and then coordinate with the local Superintendent Registrar for the district where the castle is located to ensure a legal officiant is available. Some castles, like Tretower Court, allow for smaller, intimate ceremonies in medieval halls, while others can host hundreds of guests in grand ballrooms or marquees on the grounds. Prices in 2026 typically start around £750 for a basic room hire for the ceremony and can exceed £10,000 for a full weekend buyout. Since Wales is a popular wedding destination, 2026 couples are advised to book at least 12–18 months in advance, especially for Saturday dates in the summer.
